我正在使用Eclipse Indigo，并且无法编译之前在Ganymede中工作正常的代码。我无法导入任何这些类：
import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.CTabFolder;
import org.eclipse.swt.custom.CTabItem;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Composite;
我尝试在Eclipse Marketplace中搜索SWT但找不到该库。另外，我读了其他文章，说重建我的项目（我做过），其他人建议下载“JAR”。有谁知道我需要下载什么JAR？或者如何修复我的构建路径，以便它包含这些SWT库？

发布的.classpath文件不包含可以加载SWT类的任何内容。这个项目不会像任何版本的Eclipse那样构建。
听起来您正在尝试构建独立的SWT应用程序（而不是说Eclipse插件）。独立应用程序需要类路径上的SWT库。您不会在Eclipse Marketplace上查找SWT，因为您没有寻找扩展Eclipse的插件。您正在寻找一个供您的项目依赖的库。您可以将SWT下载为在系统上某处提取的zip。该zip包含.jar文件和属于SWT实现的本机库。
我会告诉你如何找到它，而不是直接给你一个链接。从Eclipse Platform下载站点开始：
http://download.eclipse.org/eclipse/downloads/
忽略开发构建。查看最新版本。现在，那将是3.7。按照指向构建页面的链接。寻找底部的SWT。下载适合您的系统的zip。提取它并从项目的类路径中添加对包含的jar的引用。
